Neuroanatomic, epigenetic, and genetic differences in monozygotic twins discordant for Attention Deficit Hyperactivity Disorder

Molecular Psychiatry, 2017
The study of monozygotic twins discordant for attention deficit hyperactivity disorder can elucidate mechanisms that contribute to the disorder, which affects ~7% of children.

The contribution of efficient production of monozygotic twins to beef cattle breeding

Journal of reproduction and development, 2017
Production of sires with high breeding potential is indispensable for prompt and reliable breeding using their semen in the cattle industry. Currently, in Japan, we aim to further the production of Japanese black sires via a new breeding system that uses

Methylomic analysis of monozygotic twins discordant for childhood psychotic symptoms

Epigenetics, 2015
Childhood psychotic symptoms are associated with increased rates of schizophrenia, other psychiatric disorders, and suicide attempts in adulthood; thus, elucidating early risk indicators is crucial to target prevention efforts.

Molar incisor hypomineralisation: current knowledge and practice

International Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

Twins and endocrinology

Indian Journal of Endocrinology and Metabolism, 2014
Twins are two independent babies delivered during the same pregnancy and are divided as monozygotic or dizygotic based on their origin. Dizygotic twins are similar to two siblings and have different genetic information.

Monochorionic diamniotic twins of discordant external genitalia with 45,X/46,XY mosaicism

Molecular Genetics & Genomic Medicine, 2020
Background Monozygotic twins with 45,X/46,XY mosaicism, discordant for phenotypic sex, are extremely rare. Methods This report describes the clinical findings of a rare case of 45,X/46,XY mosaicism in monozygotic twins with different external genitalia ...

Monozygotic twins discordant for homologous Robertsonian translocation trisomy 21 of 46, XX, + 21, der (21;21) (q10; q10) in a twin-to-twin transfusion syndrome, case report

BMC Pregnancy and Childbirth, 2021
Background Monozygotic twins are nearly identical in genotype and phenotype because monozygotic twins arise from one fertilized oocyte. In all cases of discordant karyotype in monozygotic twins, trisomy 21 accounts for about one in 385,000.

Atomistic mechanisms of twin-twin interactions in Cu nanopillars [PDF]

Computational Materials Science 185 (2020) 109950, 2020
Twinning is an important mode of plastic deformation in metallic nanopillars. When twinning occurs on multiple systems, it is possible that twins belonging to different twin systems interact and forms a complex twin-twin junctions. Revealing the atomistic mechanisms of how twin-twin interactions lead to different twin junctions is crucial for our ...

Spatial Coherence of Oriented White Matter Microstructure: Applications to White Matter Regions Associated with Genetic Similarity [PDF]

NeuroImage (2018), 2018
We present a method to discover differences between populations with respect to the spatial coherence of their oriented white matter microstructure in arbitrarily shaped white matter regions. This method is applied to diffusion MRI scans of a subset of the Human Connectome Project dataset: 57 pairs of monozygotic and 52 pairs of dizygotic twins.
